There are two special dangers to which law, and society which is held together by law, appear to be liable in their infancy. One of them is that law may be too rapidly developed. This occurred with the codes of the more progressive Greek communities, which disembarrassed themselves with astonishing facility from cumbrous forms of procedure and needless terms of art, and soon ceased to attach any superstitious value to rigid rules and prescriptions. It was not for the ultimate advantage of mankind that they did so, though the immediate benefit conferred on their citizens may have been considerable. One of the rarest qualities of national character is the capacity for applying and working out the law, as such, at the cost of constant miscarriages of abstract justice, without at the same time losing the hope or the wish that law may be conformed to a higher ideal. The Greek intellect, with all its nobility and elasticity, was quite unable to confine itself within the strait waistcoat of a legal formula; and, if we may judge them by the popular courts of Athens, of whose working we possess accurate knowledge, the Greek tribunals exhibited the strongest tendency to confound law and fact. The remains of the Orators and the forensic commonplaces preserved by Aristotle in his Treatise on Rhetoric, show that questions of pure law were constantly argued on every consideration which could possibly influence the mind of the judges. No durable system of jurisprudence could be produced in this way. A community which never hesitated to relax rules of written law whenever they stood in the way of an ideally perfect decision on the facts of particular cases, would only, if it bequeathed any body of judicial principles to posterity, bequeath one consisting of the ideas of right and wrong which happened to be prevalent at the time. Such a jurisprudence would contain no framework to which the more advanced conceptions of subsequent ages could be fitted. It would amount at best to a philosophy marked with the imperfections of the civilisation under which it grew up.
Few national societies have had their jurisprudence menaced by this peculiar danger of precocious maturity and untimely disintegration. It is certainly doubtful whether the Romans were ever seriously threatened by it, but at any rate they had adequate protection in their theory of Natural Law. For the Natural Law of the jurisconsults was distinctly conceived by them as a system which ought gradually to absorb civil laws, without superseding them so long as they remained unrepealed. There was no such impression of its sanctity abroad, that an appeal to it would be likely to overpower the mind of a judge who was charged with the superintendence of a particular litigation. The value and serviceableness of the conception arose from its keeping before the mental vision a type of perfect law, and from its inspiring the hope of an indefinite approximation to it, at the same time that it never tempted the practitioner or the citizen to deny the obligation of existing laws which had not yet been adjusted to the theory. It is important too to observe that this model system, unlike many of those which have mocked men's hopes in later days, was not entirely the product of imagination. It was never thought of as founded on quite untested principles. The notion was that it underlay existing law and must be looked for through it. Its functions were in short remedial, not revolutionary or anarchical. And this, unfortunately, is the exact point at which the modern view of a Law of Nature has often ceased to resemble the ancient.
